الأسئلة الشائعة
How does offline client-side image compression work?
It leverages background Web Workers, HTML5 Canvas, and WebAssembly codecs to compress pixel buffers directly in browser memory.
Can I use this compressor without an internet connection?
Yes. Once cached, all scripts and worker engines run entirely offline, allowing you to compress and download images without connectivity.
